Allen Bradley Type A Residual Current Device Switch, 40A Current Rating, 100mA Trip Sensitivity - 1492-RCDA4B40

Safely detect problems in your electrical circuits with this residual current device (RCD) switch from Rockwell Automation's Allen Bradley range. It automatically disconnects a circuit's conductors when it breaks, minimising the risk of shocks and electrical fires. The switch's instantaneous break time ensures a fast response for a high level of workplace safety. Thanks to its broad operating temperature range of -25°C to +55°C, it's suitable for use in demanding environments.

• Type A breaker is compatible with AC or DC power for versatile use

• Toggle switch reset actuator for a simple reset after tripping

• Designed for fast-clip DIN rail mounting to save time and effort during installation

• Long mechanical lifespan of 20,000 operations for long-lasting performance

Standards and Certifications

• CE (Conformitè Europëenne)

• UKCA (UK Conformity Assessed)

• UL (Underwriters' Laboratories)

• RoHS (Restriction of Hazardous Substances)

What kinds of faults cause an RCD to trip?

An RCD detects a dangerously high current in your circuit and trips to prevent the current from causing damage. The most common causes of a high current include loose electrical connections, damaged or faulty wiring, adverse weather conditions and moisture in the circuit or a connected appliance.

1492 Series

Allen Bradley general purpose RCDs from the 1492 series. The RCDs have a Type A tripping characteristic and an instantaneous break time. 2 or 4 pole versions available. All the RCDs incorporate screw terminals and can be DIN Rail mounted.
